For the last few years I've been tracking the user location of personality tests taken on this site so as to gather data on geographic personality differences on eight core personality traits (Materialism, Offbeat, Thinking, Interpersonal, Vital, Easygoing, Sectarian, Scientific, and Artistic). You can now view that data in sortable/searchable spreadsheets here - http://similarminds.com/vizdb/cities.html. I've omitted countries/regions/cities where there was not enough records to reach a level of reasonable statistical significance (below 900 records), but the database as a whole is now over a million records.

It's important to note that the data of more non-english speaking countries will be less representative of the general population, and will skew towards foreign nationals and more educated nationals.
